Codenames is a module. It became semi-official in September 2022.
The module is based on the board game Codenames.
Gameplay
Codenames is a game for two teams. There is a grid of 25 words. Some of them are secretly assigned to the Red Team, some to the Blue Team. One player from each team is the Spymaster, and only Spymasters see which words belong to which team. Spymasters take turns giving clues to their Operatives, trying to lead them to guessing their team's words. The team that guesses all their words first wins the game.
Teams
One player from each team should click on Join as Spymaster. They will then see the colors of the cards. Everyone else should click on Join as Operative. They do not see the colors of the cards. Click your username to leave your team, you are able to do that on lobby.
Clues
Spymasters give clues. When it's your turn to give clue, an input and number board will appear on the screen. You must type one word clue in the input, select how many cards are related with this word on the number board then click the send button to make your clue official. Your Operatives will only see the clue and the number of related cards.
Guessing
Operatives guess the words based on the Spymaster’s clue. You can discuss the clue with your teammates. You can also suggest a guess by tapping the card you think matches the clue. Half of your teammates must vote for the same word to make guess official. If you guess a word of your team's color, you may guess again. You'll want to guess as many words as your Spymaster indicated.
